Fig. 3 is a sectional view through the device on line 33 of Fig. 1. Figfil is a sectional View and'end elevation on line H of Fig; 2, but on a larger scale, and Fig. 5 is an enlarged cross section on line 5 5 of Fig. 1.

The ordinary fountain pen' comprises a barrel having a tubular pen'holding part or section -b screw-connected with one end of said body or barrel, and a' detachable cap adapted to have a slip or screw-connection with section -Z) or the barrel. A feed bar c or corresponding element is usually s'ecured within section .-b and in some instances element c is' providedv with a narrow slot or. chamfer for feeding the ink from the barrel or from a collipsible ink tube (not shown) but usually attached to detachable section -b. This tubular section bcontaining feed bar cis frequently clogged with dry ink, or substances drawn in from the ink well or bottle in filling the fountain pen. Cleaning of the pensection is'diificult on account of the small ink passage therein and "can "only fbei successfully. accomplished from the inner e111d ofthe pen section and by dissolving the 1n r.

tion while thiss'ection' is clamped or held tightly in sealedunion withjone end'jof-"a' pump cylinder so that a thoroughcleaning- As shown, the device COIHPI at its ends.

Thepres'ent device or instruinent 'is designed to force a stream of water or other .liquidunder pressure through the'pen sec of the pen may be accomplishedwithout-' soiling the hands or clothes, 5

isesa hollow pump cylinder or barrel 2"wh'ich .is screw ,th'readedexternally at its middle andfalso A head S-carrying ap'air of pivotedfingers or clamping members s and 5- is aflixed toone, end of barrel 2, and a tubular'part :6 is removably' screwed or connected to head 3. The outer end edgeaii'of part6, is smoothly finished to" seat a sealing washeror gasket 8,*and the pen section' 'b' which is to becleanedis inserted into the open end of part 6 until the annular shoulder 9 on the pen section engages the sealing washer 8,'see Fig.- 3. 'Pen sectioni position by means of clamping m'embers 5 downwardly extending arms 10 'slottedf at:

12 is connected to a cam lever 13 pivotally and 1, respectively, each of which have. 1

. their extremities to receive the'hooltends 117 1 of a pair of operating links '12. 'Each link mounted upon a loose sleeve 14 opposite an.

adjustable screw collar 15 onbar'relQ. The

clamping members are open when the levers are turned upwardly and outwardly Has. shown 1n dotted lines'ln F 1g. 1, andlockedi and clamped upon pen section'l iw henp the lovers are turned downwardly as shown in full lines in the same figure. In clamping the pen section it, is drawn downwardly so that the shoulder 9 is pressed tightly against the sealing washer which is pressed ,in turn against the end edge 7 off the tubular receiving part 6. I

Cylinder or barrel 2 contalns a'recipr'ocable plunger or piston carrying leather packing 16, and a piston rod 17 extends ,through a screw cap or guidemember 18 at the outer end of'the cylinder or barrel and terminates in a handle 19' topermit; convenient reciprocable operation of the piston."

Thus in using the instrument the pen sec tion b of .a fountain pen is detached from its ink reservoir or tubeand: inserted into the tubular part or adapter member 6 and seated against the sealing washer as shown in Fig. 3. Collar 15 is adjusted on barrel 2 to permit a good clamping connection to be made with the particular type or kind of pen section bto be cleaned,

and then the cam levers 13 are pressed downwardly until the clamping fingers or members 4 and 5 grip the pen section and press it downwardly against sealing washer 8. This is preferably done by holding the device in one hand and using the fingers of the same hand to press the levers, while the other hand is used to grip handle 19 and reciprocate piston rod 17. In this operation tions of diti'erent sizes and kinds as illustrated in Fig. 15. k
